About Me

I'm a Senior Full Stack Engineer based in India with over 5 years of experience building production-grade web applications across fintech, EdTech, and SaaS domains.

Currently leading full-stack development at Zedpe, where I architect and ship a UPI payment gateway handling 10M+ monthly transactions with event-driven microservices, GraphQL APIs, and Redis-backed reliability mechanisms.

I care deeply about system reliability, clean architecture, and leveraging AI-assisted workflows to accelerate engineering velocity. I hold a B.Tech in Computer Science.
